# Acceleration along a 2D plane

It's been a long time since I've done trig, and I never new it very well. I have a problem I don't know how to solve.

I have an object on a 2D plane that I want to move. I have this objects x and y coordinates, I also have it's velocity, and the angle of the velocity in radians.

How can I take this information and calculate velocity long the X axis and Y axis. I.E., how can I convert the angle and velocity to the delta of X and Y?

Sounds like a case of using parametric equations. –  Hawk Jun 29 '12 at 2:09

$v_x = v\cdot \cos(\theta)$
$v_y = v\cdot \sin(\theta)$
